Characterization of silver and silver chloride nanoparticles (Ag/AgCl NPs) synthesized using culture supernatant of nutrient broth (NB)-grown T. pantotropha and AgNO₃ at 37 °C and pH 7 a UV–Vis spectra of NB control and Ag/AgCl NPs synthesized at varying AgNO₃ concentration, b XRD spectra of Ag/AgCl NPs synthesized using 2 mM AgNO₃, and FEG-TEM images of Ag/AgCl NPs synthesized using c 1 mM AgNO₃, d 2 mM AgNO₃ and e 5 mM AgNO₃. The inset in a depicts the visual appearance of the NB control and Ag/AgCl NP suspensions synthesized at varying AgNO₃ concentration
